pickup clarity issues plague the Gibson models as well. it seems that the manufacturer has a reserved mindset when it comes to certain ideas that work for the Les Paul. i do not blame this restrain, it's all in the name of preserving a well-loved tradition; some people swear by the muddy 'woman tone' of the LP.
the problem with Epi LPs, on a personal note, is that there's a less faithful recreation of the real thing. it's all understood because Epiphone works on a different priciple than Gibson, especially so in terms of production costs. however, much can be done if Epi takes the cue from Burny/ Tokai (among others) which offer a more palatable offering.
